# What this PR does
The current implementation of the direct paging feature doesn't page
additional responders if the alert group is acknowledged, silenced, or
resolved, and doesn't show any warnings for such cases.
This PR makes so that adding responders for silenced & acknowledged
alert groups actually pages the selected user / schedule. For resolved
alert groups, a warning message will be shown both in web UI and Slack.
